Async Callbacks via Bindless References

In this mode, a source component uses a reference that does not include a binding, which is then wired to a target component via a service that does not include a binding either. For an example, see the inner.composite sample. To illustrate, an excerpt of the SCDLs for the inner.composite sample is as follows:

Async Callbacks via WS/Axis2 Binding

In this mode, the reference and service used by the source and target components use a WS/Axis2 binding (<binding.ws/>). For an example, see the helloworldws-async and helloworldwsclient-async samples. A preview of the SCDLs is as follows:
